BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] The invention relates to a method for manufacturing of a meshjewel.

[0004] 2. Description of the Related Art

[0005] For producing jewels, high purity precious metals, for exampleplatinum, gold or silver are generally used. High purity precious metalshave a very high specific weight and they are very expensive,consequently large size jewels made of these metals are relatively heavyand expensive. Heavy jewels cause discomfort to people wearing them, andthe high price does not allow a broader distribution of these jewels. Inaddition, it is a known fact that relatively thick pure precious metalpieces are difficult to machine, i.e. that they are difficult to cut,bend and draw.

[0006] A known solution for eliminating these problems in the jewelindustry is the producing of so called mesh jewels, which comprise amesh made of precious metal wire, arranged in a plane or along a threedimensional surface. This mesh enables the manufacturing of large size,attractive and yet low weight and not too expensive jewels.

[0007] A mesh jewel and a method for its manufacturing are described forexample in EP 0 495 100 A1. This known mesh jewel comprises a preciousmetal mesh arranged in a plane and fitted in a precious metal setting.The precious metal mesh is produced by laying at random a large numberof metal wires bent in different shapes, followed by pressing, and thenthe metal wires are fixed to each other at the nodes. This fixing can befor example a diffusion joint assisted by heat treatment. Next, the meshis subjected to cold working, polishing and then it is placed into thesetting. This known method is primarily suitable for producing meshesarranged in a plane, and the mesh may not have a complicated threedimensional shape. In the case of a larger surface mesh, another problemarises, namely that the mesh will not be sufficiently rigid and in thecourse of use the mesh jewel is subjected to a permanent deformation.Furthermore, this known method does not enable the fitting of decorativeelements along the surface of the mesh.

[0008] Another solution known to the jewel industry is when—by themanual arrangement of the precious metal wire—a three dimensional meshsurface is formed, and the wire nodes are soldered or welded one by one.This solution, however, does not allow the accomplishing of sufficientrigidity in the case of larger size jewels, and it is very difficult tofit decorative elements along the three dimensional surface.

[0009] A further mesh jewel and a method for its manufacture aredescribed in DE 29 19 912 A. This mesh jewel comprises node elements atcrossings of the metal wire sections forming the mesh. The node elementsare formed as balls having two through bores arranged in crosswisedirection to each other through which the wire sections are inserted.These node elements are, however, difficult and costly to manufacture,and do not allow the crossing of more than two wire sections at a node.Furthermore, there is no teaching in DE 29 19 912 A about fixing thesenode elements in space. Therefore, this known mesh jewel can not bemanufactured with a dense mesh and with a sufficient rigidity.

SUMMARY OF THE INVENTION

[0010] It is an object of the invention to provide a mesh jewelwhich—with a relatively low weight—has sufficient rigidity even in thecase of larger dimensions to prevent permanent deformation even duringprolonged use, and which enables the fitting of decorative elementsalong the mesh of the mesh jewel. It is another object of the inventionto provide a simple and cost-efficient method for manufacturing the meshjewel.

[0011] According to a first aspect, the invention is a mesh jewelcomprising a mesh formed by at least one metallic wire section arrangedalong a mesh surface, wherein the mesh comprises nodes located atadjoining wire section parts of said at least one wire section, andwherein at least, some of the nodes are formed with a node elementfixing the adjoining wire section parts together. According to theinvention, the mesh jewel has node elements comprising a pin arranged incross direction to the mesh surface, wherein the wire section partsadjoining the pin are tangential to or bent on the pin, and wherein endsof the pin are closed by retaining means so as to prevent displacementof the adjoining wire section parts in an axial direction of the pin,said retaining means comprising a retaining element arranged at an endof the pin.

[0012] The inventive mesh with the node elements results in a higherrigidity mesh jewel, which enables the manufacturing of larger and thusmore decorative jewels with a low total weight. In addition, the higherrigidity further reduces the risk of permanent deformation when thejewel is in use. Furthermore, the node elements—by themselves or withdecorative elements fixed to them—are suitable for creating a moreattractive jewel.

[0013] In a particularly preferred embodiment, the retaining element canbe formed for example as a flange, a ball having a bore, a settingholding a gem, or a soldered, welded, bonded or adhesive closing. Theretaining elements can be fitted onto the end of the pin and fixed tothe pin by soldering or welding, but they can be is formed integrallywith the pin as well.

[0014] The mesh can be made more rigid, if the wire section partsadjoining the pins of the node elements are fixed to the node elementsby soldering or welding. The at least one wire section is tangential toor bent on the pins of the node elements, and passes by the pins atleast twice from different directions.

[0015] The mesh surface can be planar, a three-dimensional curvedsurface or a three-dimensional surface defined by planes.

[0016] In another preferred embodiment, the mesh jewel comprises alatticework formed along the mesh surface, wherein the at least one wiresection is arranged along a surface of the latticework and is attachedto node elements fixed to lattice knots of the latticework. In thisembodiment the latticework ensures the spatial fixing of the nodeelements. The fixing of the node elements is very important because inthis way the wire section can be tightened on the pins of the nodeelements, thereby providing a more rigid structure. In this way, thelatticework according to the invention allows the producing of a morerigid mesh jewel, which is larger and thus more decorative, with a lowtotal weight. The higher rigidity also reduces the risk of the jewelsuffering a permanent deformation while being worn.

[0017] In a further preferred embodiment the mesh jewel comprises arigid jewel body to which the mesh is attached by means of through holesor fixing node elements secured to the jewel body. In this case the nodeelements can be fixed to the jewel body by means of distance rods,thereby resulting in a more rigid jewel.

[0018] Parts of or the entire mesh jewel can be preferably formedintegrally by casting. The material of the inventive mesh jewel can beplatinum, gold, silver, titanium and/or stainless steel.

[0019] According to a second aspect, the invention is a method formanufacturing a mesh jewel, comprising the steps of forming a mesh withat least one metallic wire section by arranging it along a mesh surface,wherein the mesh comprises nodes at adjoining wire section parts of saidat least one wire section, and wherein at least some of the nodes areformed with a node element fixing the adjoining wire section partstogether, characterised by arranging pins in cross direction to the meshsurface, and arranging said at least one wire section so as to passtangentially to or bent on the pins and attaching ends of said at leastone wire section to the mesh jewel, wherein ends of the pins are closedby retaining means so as to prevent displacement of adjoining wiresection parts in an axial direction of the pin, said retaining meanscomprising retaining elements arranged at the ends of the pins.

[0020] By means of the method according to the invention, a mesh jewelwith a higher rigidity can be manufactured simply and with a relativelylow cost. The inventive method enables simple fitting of decorativeelements along the surface of the mesh.

[0021] For forming the mesh, preferably a shaping piece having a surfacecorresponding to the mesh surface can be used. The shaping piece can beplaced onto a rigid jewel body, and the at least one wire section can bearranged fixedly attached to the jewel body. The shaping piece ispreferably made of a material completely removable by heat treating orby applying a solvent.

[0022] By means of the shaping piece, on the one hand the wire sectioncan be guided in a way that it is adjusted to the surface of the shapingpiece, and on the other the node elements are thereby spatially fixed.Fixing the node elements is very important because in this way the wiresection can be tightened on the pins of the node elements, therebyensuring a more rigid structure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0035] The mesh jewel depicted in FIG. 1 is a ring which comprises amesh made of one or more wire sections 4, and a rigid jewel body 11, towhich the mesh is fixed. Nodes of the mesh are formed with node elements1 arranged along a spherical surface, which node elements 1 comprise apin 2 arranged crosswise to the spherical surface, a retaining element 3arranged at an inner end of the pin 2, and a retaining element 5arranged at an outer end of the pin 2. In the depicted embodiment, theretaining elements 3 and 5 are flanges, which are pulled on the ends ofthe pin and fixed there by welding or soldering. These flanges ensurethat wire section parts passing by the node elements 1 are prevented indisplacement in an axial direction of pin 2, thereby enabling the designof a rigid mesh. Node elements 1 are secured to the jewel body 11 bymeans of distance rods 8 in a way that the distance rods 8 are fittedinto bores in jewel body 11, and fixed there by welding or soldering.The distance rods 8 serve as a firm support for the node elements 1,thereby increasing the rigidity of the mesh jewel. The distance rods 8are not necessarily placed into bores, but they can also be welded orsoldered to the wall of the jewel body 11.

[0036] On an external lateral surface of an upper flange part of thejewel body 11 there are fixing node elements 1′ uniformly distributed ina circle, and they fix the mesh to the jewel body 11. Fixing pins 2′ ofthe fixing node elements 1′ are located in bores of jewel body 11, andfixed there by welding or soldering. The fixing node elements 1′comprise a retaining element 5′ arranged at an outer end of the fixingpins 2′, which retaining element is formed as a flange in the embodimentshown. This flange prevents the wire section parts adjoining the fixingpins 2′ in coming off the retaining pin 2′. It is not necessary tolocate the fixing pins 2′ in bores, but they can also be welded orsoldered to the wall of jewel body 11.

[0037] As it will be shown more detailed later on, the wire section 4 isarranged on the pins 2 of the node elements 1 located along thespherical surface in a manner that it touches the pins 2 withoutchanging direction or is bent on them, and it returns to the pins 2repeatedly from different directions, so that the pins 2 are surroundedby wire section 4. Parts of the wire section 4 touching the pins 2 and2′ may be fixed by laser spot welding or soldering to respective nodeelements 1 and 1′.

[0038] In the manufacturing method of the preferred embodiment as perFIG. 1, as shown in FIGS. 2 to 8, first a shaping piece 10 having asurface corresponding to a three dimensional mesh surface to be formedis produced. The shaping piece 10 is produced of a material that can befully removed by heat treatment or by using a solvent, preferably wax,for example by carving or modelling. Next, elements consisting of theretaining element 3 formed as a flange and the pin 2 are secured bymeans of the distance rods 8 to the jewel body 11, wherein the jewelbody 11 is matched in shape to the shaping piece 10. The distance rods 8may be formed as extensions of the pins 2, but they can also be designedas separate elements, fixed to the pins 2 by welding or soldering.

[0039] Furthermore, on the external lateral surface of the upper flangepart of the jewel body 1, bores located at equal spacing are formed toreceive fixing pins 2′, which are secured in the bores by welding orsoldering.

[0040] Next, the spacing structure fitted on the jewel body 11 asdescribed above is heated up and the shaping piece 10 is pulled onto thestructure. When fitting the shaping piece 10, bulges appearing on itssurface are smoothed and so the interim phase shown in FIG. 4 isobtained. The shaping piece 10 fixes the pins 2 and this offers anespecially advantageous hold for the spacing structure when arrangingthe wire section 4 and when tightening the same.

[0041] In the next step, by arranging the wire section 4 on the pins 2and 2′, a mesh matched to the surface of the shaping piece 10 is formed.The mesh is made of one or more wire sections 4, the thickness of whichis preferably between 0.1 and 0.5 mm. Prior to forming the mesh, one endof the wire section 4 is fixed to one of the pins 2 or 2′. When makingthe mesh, the aesthetic appearance of the mesh jewel is to be ensured,and hence, if possible, repeated parallel running of the wire section 4is to be avoided. Therefore, the wire section 4 is preferably guided ina zigzag shape by bending it on pins 2, 2′ as depicted in FIG. 5, andthen wire section 4 is repeatedly returned from different directions tothe pin 2, 2′ and it is thereby surrounded from several directions bythe wire section 4. This guiding manner of the wire section 4 isadvantageous for the aesthetic impact and also for the rigidity of themesh jewel. The wire section 4 is tightened between the node elements 1and 1′ in a way that the wire section 4 rests on the surface of theshaping piece 10. Next, the free end of the wire section 4 is fixed toone of the node elements 1. Thereby a mesh surface following the curvedsurface of the shaping piece 10 is obtained. Wire section parts 4 a, 4b, 4 c, and 4 d adjoining the node elements 1 can be fixed by welding orsoldering to the node elements.

[0042] After creating the mesh, as depicted in FIGS. 6 to 8, retainingelements 5 formed as a flange are pulled onto the pins 2, protrudingparts of the pins 2 are cut off, the retaining elements 5 are welded orsoldered to the pins 2, and the external surface of the so formed nodeelements 1 is smoothed and polished. In this way, flange retainingelements 3 and 5 associated with the node elements 1 surround the wiresection parts 4 a, 4 b, 4 c, and 4 d bent on the pin 2. The fixing nodeelements 1′ can be produced in an identical way with the difference thatthe wire section parts adjoining the pins 2′ are supported by theexternal wall of the jewel body 11 and the by retaining elements 5′.Next, the shaping piece 10 is removed by heat treatment or by using achemical solvent. In this way the mesh jewel shown in FIG. 1 is created.

[0043] According to the invention, instead of the fixing node elements.1′, throughholes formed in the jewel body 11 can be applied as well forfixing the mesh, when during the producing of the mesh, the wire section4 is looped by guiding it through the through-holes.

[0044] It can be advantageous that the wire section is not guided alonga curved surface between the node elements, but along the shortestpossible path in a straight way. In the course of manufacturing thisembodiment, distance rods are fixed to the jewel body by welding orsoldering, and then the spacing structure is heated up and the shapingpiece made of thermoplastic material is pulled onto the spacingstructure. In this embodiment, the shaping piece is necessary to be ableto adjust the lengths of the distance rods according to the surface ofthe shaping piece, thereby arranging the node elements along therequired surface. Next, the node elements are formed at the ends of thedistance rods adjusted to the surface of the shaping piece or they aresecured to the distance rods. Prior to making the mesh, the shapingpiece is removed and then the wire section is arranged along theshortest path possible between the node elements. This embodiment isadvantageous, because the wire section between the nodes is not soeasily loosed, if it is guided along the shortest path possible.

[0045] FIGS. 9 to 11 depict the steps of manufacturing a preferredembodiment of the invention, where distance rods are not used, and thenode elements 1 are designed unsupported, they are only fixed by themesh formed of wire section 4. This embodiment can be usedadvantageously when the mesh can be formed in a sufficiently rigid wayto make sure that it is not subjected to permanent deformation evenduring prolonged use, and in case the mesh jewel is not subjected to anyspecial mechanical load during use.

[0046] The manufacturing of this embodiment also starts with the formingof shaping piece 10. Next, elements comprising the retaining element 3formed as a flange and the pin 2 are fixed to the surface of the shapingpiece 10. The fixing is preferably implemented by bonding or by meltinginto the shaping piece 10.

[0047] Again, in a uniformly spaced way, bores are formed on theexternal lateral surface of the upper flange part of the jewel body 11,into which the fixing pins 2′ are placed an fixed there by welding orsoldering.

[0048] Next, the shaping piece 10 is placed on the jewel body 11,thereby accomplishing the interim phase depicted in FIG. 11.

[0049] In the next step, the mesh consisting of the wire section 4 isprepared as described above. After the forming of the mesh, retainingelements 5 and 5′ are pulled onto the pins 2 and 2′, the protrudingparts of the pins 2 and 2′ are cut off, the retaining elements 5 and 5′are fixed by welding or soldering to the nodes, and then the externalsurface of the node elements 1 and 1′ are smoothed and polished. Next,the shaping piece 10 is removed as described above.

[0050] Retaining elements 3 and 5 with the pin 2 can be preferably madeintegrally, for example by lathe machining. In this case node elements 1made integrally are fixed by distance rods to the jewel body or fittedon the surface of the shaping piece 10. In this embodiment, once themesh is formed, the shaping piece can be immediately removed, because itis not necessary to close the pins. Furthermore, node elements 1 madeintegrally are advantageous, because a recessed setting can be formed inthem for a gem on an external side of the retaining elements.

[0051] Manufacturing of another preferred embodiment of the mesh jewelaccording to the invention begins as depicted in FIG. 12 in a way thatthe rigid jewel body 11 is formed as an annular frame made of solidmetal. In an upper flange section of the jewel body 11, equally spacedbores are formed in which fixing pins 2′ are placed and fixed by weldingor soldering. Next, a shaping piece 10 having a surface corresponding toa three dimensional mesh surface to be created is placed onto the jewelbody 11. In the depicted preferred embodiment, the three dimensionalmesh surface is a spherical surface.

[0052] In the next step shown in FIG. 13, a latticework 12 resting onthe surface of the shaping piece 10 is formed, and then in crossdirection to the mesh surface, pins 2 are fixed to the lattice knots ofthe latticework 12.

[0053] In the next step, the shaping piece 10 is removed for example byheat treatment, thereby accomplishing the skeleton structure shown inFIG. 14.

[0054] Subsequently, as shown in FIG. 15, by arranging the wire section4 on the pins 2 and 2′, a mesh arranged along the latticework 12 isformed. Between the node elements 1 and 1′, the wire section 4 istightened in a way that the wire section 4 follows the surface of thelatticework 12. Thereby a mesh following the curved surface of thelatticework 12 is obtained. The wire section parts passing by the nodeelements 1 or 1′ may be fixed by welding or soldering to the nodeelements 1 or 1′.

[0055] After creating the mesh, protruding parts of the pins 2 and 2′are cut to size, retaining elements are pulled onto them, and then theretaining elements are welded or soldered to the pins 2 and 2′. In sucha way, node elements 1 and 1′ are formed, where the latticework 12 andthe retaining elements surround the wire section parts adjoining thepins 2 and 2′. After these steps, the mesh jewel depicted in FIG. 15 isobtained.

[0056] Deviating from the above-described methods, the mesh jewel mayalso be manufactured by employing a casting method known per se. Forexample it is possible to produce the rigid jewel body 11 with thefixing pins 2′ and the latticework 12 with the pins 2 integrally bycasting. To this end, of course it is necessary to form a master patternin a way described above, to produce the mould in a manner known per se.The workpiece produced by casting can then be subjected to a deburringand/or polishing method known per se, followed by the forming of themesh on it, and the closing of the ends of the pins 2 and 2′. In thegiven case, the total mesh jewel, i.e. the rigid jewel body 11 with thefixing pins 2′, the latticework 12 with the pins 2 and the mesh and theclosings can be produced integrally by casting.

[0057] If this is required by the desired aesthetic effect, some of theopenings of the latticework 12 can be covered by embossed or flatplates. The plates can be fixed by soldering or welding on thelatticework 12, but they can also be produced by the above castingmethod. The openings can for example be covered in a chessboard pattern.

[0058] In the depicted preferred embodiment, the latticework 12 followsa pattern consisting of equilateral triangles, but it can also bedesigned in a square, hexagonal or random pattern.

[0059]FIG. 16 shows a partial sectional front view of the mesh jewelmade by the method shown in FIGS. 12 to 15. The nodes of the latticeworkof the mesh jewel are formed with node elements 1 arranged along thespherical surface as described above, which node elements 1 comprise thepin 2— arranged crosswise to the spherical surface—and the retainingelement arranged on the outer end of the pin 2. In the depictedembodiment, the retaining elements have a ball shape fitted with a boreand they are pulled onto the ends of the pins, where they are fixed bywelding or soldering. These retaining elements prevent the wire sectionparts adjoining the pins of the node elements 1 in displacing in thedirection of the axis of pins two, thereby allowing the creation of arigid mesh. The latticework 12 serves as a firm support for the nodeelements 1, thereby increasing the rigidity of the mesh jewel.

[0060] The fixing node elements 1′ comprise retaining elements arrangedat an outer end of the fixing pins 2′, which retaining elements are,designed in the embodiment depicted as balls fitted with a bore. Theseretaining elements prevent the wire section parts passing by the fixingpins 2′ in coming off the fixing pins 2′. It is not necessary to fit thefixing pins 2′ in bores, but they may also be welded or soldered to thewall of the jewel body 11.

[0061] As already described above, the wire section 4 is arranged on thepins 2 of the node elements 1 arranged along the surface of thelatticework 12 and on the pins 2′ in a way that it is in contact withoutchanging direction or is bent on the pins 2 and 2′, repeatedly returnsfrom different directions to and surrounds each pin 2 and 2′. The wiresection parts in contact with pins 2 and 2′ may be fixed by laser spotwelding or soldering to the node elements 1 and 1′.

[0062] In FIGS. 17 and 18, the steps of manufacturing a node element 1as per FIG. 16 can be seen. For forming the node element 1, first thecylindrical pin 2 is fixed by welding or soldering to the latticework12. After arranging the wire sections 4 according to the descriptionabove, the protruding part of the pin 2 is cut to size and the free endof the pin 2 is closed by a ball shaped retaining element 13. In theball shaped retaining element 13 a bore is formed, which is pulled ontothe free end of the pin 2, and then the retaining element 13 is fixed bywelding or soldering.

[0063] The node element 1 shown in FIG. 19 is closed by a solderedclosing 9. When creating the closing 9, the solder runs into and betweenthe wire section parts bent around the pin 2, and secures the wiresection parts to the pin 2 and to the latticework 12. The melt generatedin the course of soldering is then removed. Instead of the solderedclosing 9, of course, a different joint may also be applied, for examplea welded or bonded joint.

[0064] In the case of another preferred embodiment shown in FIGS. 20 and21, the free end of the pin 2 is closed with a retaining element 6formed as a setting, wherein the latticework 12 and the setting surroundthe wire section parts adjoining the pin 2. The setting preferablyreceives a gem 7. The setting, which further improves the aestheticappearance of the mesh jewel, is also fixed by welding or soldering tothe pin 2.

[0065] The mesh jewel according to the invention is not limited to theembodiments described above, but may also be formed in a different way.It is possible for example to create a mesh jewel without a rigid jewelbody, when the mesh preferably forms a closed body, for example a globeor a spatial heart shape. In the course of manufacturing thisembodiment, the pins fitted with retaining elements are fixed to thesurface of the shaping piece, the mesh is formed on the surface of theshaping piece, the free ends of the pins are closed and then the shapingpiece is removed. In another embodiment, a latticework is formed on thesurface of the shaping piece, pins are fixed to the lattice knots of thelatticework, the shaping piece is removed, the at least one wire sectionis arranged as described above, and the free ends of the pins areclosed. The casting step described above can be applied of course in thecase of these embodiments as well. These embodiments are advantageous ifthe mesh jewel can be designed in a sufficiently rigid manner so that itdoes not suffer permanent deformation in the course of prolonged use,and if the mesh jewel is not subjected to any special mechanical loadwhile being worn. Such a mesh jewel can be for example an ear-ring, apendant etc.

[0066] At the ends of the pins, the retaining elements may not only bedesigned as a flange, ball or setting. For example the end of the pincan be melted, thereby forming a melt sphere at the end, and then themelt sphere is cooled. The retaining element so designed cansufficiently prevent the displacement of the wire section parts passingby the pin in the axial direction of the pin.

[0067] The mesh, the nodes and in the given case the jewel body may bemade of the same precious metal, but if a varied colour effect is to beaccomplished, different precious metals can be applied for each element.For example, a platinum wire can be soldered with pure gold. Thematerial of the mesh jewel can be for example silver, white gold, greengold, red gold, pure gold, platinum, titanium or stainless steel.
